In dogs, genes a and b are required for scent. individuals homozygous for either one or both of the nonfunctional recessive alleles are not able to smell. if a large number of matings were made between two double heterozygotes, what percentage of offspring would not be able to smell? express your answer as a fraction (i. e. 1/10)

6/16 dogs will not be able to smell.

Explanation:

Genes A and B are considered for scent smell.

Individuals homozygous for either one or both of the nonfunctional recessive alleles are not able to smell.

The final cross would be AaBb x AaBb which has outcome of;

Individual with homozygous nonfunctional recessive alleles (bold ones):

the backbone of the dna and rna compound is sugar phosphate.
